93L28 Dual 8-Bit Shift Register
June 1989
93L28
Dual 8-Bit Shift Register
General Description
The 93L28 is a high speed serial storage element providing
16 bits of storage in the form of two 8-bit registers. The
multifunctional capability of this device is provided by sever-
al features: 1) additional gating is provided at the input to
both shift registers so that the input is easily multiplexed
between two sources; 2) the clock of each register may be
provided separately or together; 3) both the true and com-
plementary outputs are provided from each 8-bit register,
and both registers may be master cleared from a common
input.

Note:
The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
